| Most professional pressure washing jobs in Madison take 30 minutes to 5 hours on site. A typical 1,500 to 2,500 square foot house wash runs 2 to 3 hours, a two-car driveway 30 to 90 minutes, and a deck or patio 1 to 2 hours. After the wash, surfaces need another 24 to 72 hours to dry, depending on the material and the weather. |
When you book an exterior cleaning, the first thing you want to know is how much of your day it will take. Is this a quick morning visit, or are you blocking off the whole afternoon?
The honest answer is that “how long” really means two things. There’s the time our crew spends on site doing the work, and there’s the time your surfaces need to dry afterward. This guide covers both, broken down by the size of your home and the surfaces we’re cleaning.
We’re a family-run team here in the Madison area, and we give you a basic timeline at the same visit where we look over the property. You’ll know what to expect before we ever pull a hose off the truck.
What Determines How Long a Pressure Washing Job Takes
Size is the headline factor, but it’s not the only one. A few things move the clock up or down on every job.
Surface material and method
Siding gets soft washed at low pressure, flat concrete moves quickly with a surface cleaner attachment, and wood decks need a slower, gentler pass. Each surface has a pace of its own, so a home with mixed materials takes a little longer than one with a single surface type.
How much buildup there is
Heavy algae, mold, and grime need more dwell time and more passes to clear fully. This is where Madison conditions come into play. Homes near Lake Mendota and Lake Monona, along with shaded and north-facing walls, tend to collect more organic growth, so those surfaces often sit at the top of the time range.
How recently the home was cleaned matters just as much. A house we wash every year comes clean quickly, since there isn’t much buildup to work through. A home that hasn’t been touched in ten or fifteen years holds years of grime that needs longer dwell time and repeat passes, so that first wash after a long gap sits at the top of the range. Once you’re on a regular schedule, later visits tend to go faster.
Access
Two-story homes, balconies, dormers, tight landscaping, and mature trees all add time. The harder a surface is to reach safely, the longer it takes to clean it well.
Setup and pack-down
Every visit includes fixed overhead. Staging the equipment, hooking up hoses, pre-treating problem areas, and packing everything back up adds roughly 15 to 30 minutes no matter how big the job is. That fixed time is why a small wash isn’t as quick as its square footage alone would suggest.
A professional crew also works faster than an untrained one, because commercial equipment pushes a higher volume of water and covers more surface per pass. Experience helps too, since there’s no learning curve on the day of the wash.
How Long a House Wash Takes by Home Size
For most homes, the size of the house is the best starting point for estimating time. Here’s how it typically breaks down for a professional soft-wash siding cleaning.
| Home Size | Typical Professional Time | Madison Note |
|---|---|---|
| Under 1,500 sq ft, 1 story | 1 to 2 hours (siding often 30 to 60 min) | Ranch homes; add time for shaded north-wall algae |
| 1,500 to 2,500 sq ft | 2 to 3 hours | Where most Madison single-family homes land |
| 2,500+ sq ft or 2-story | 3 to 5 hours | Extra time for balconies, dormers, and lake-side growth |
Larger two-story homes and properties close to the lakes trend toward the higher end of these ranges, since there’s more surface to cover and often more algae to treat. If you’d like a firm number for your specific home, our professional house washing estimate includes a timeline built around your property.
How Long Driveways, Decks, Patios, and Fences Take
Plenty of homeowners bundle a few surfaces into one visit. Here’s how the common add-ons break down on their own.
| Surface | Typical Professional Time | Notes |
|---|---|---|
| Siding (soft wash) | 30 min to 3 hrs by size | Includes 5 to 10 min detergent dwell per section |
| Driveway (2-car) | 30 to 90 minutes | Surface cleaner speeds it; oil or rust pre-treat adds time |
| Deck or patio | 1 to 2 hours | Wood needs a gentler pass than composite or concrete |
| Fence | 2 to 4 hours | Depends on length and organic growth |
| Setup and pack-down | +15 to 30 minutes | Fixed overhead on every visit |
When you combine surfaces, the times stack, but the setup only happens once. That makes a bundled visit more efficient than booking each surface on a separate day. If you’re adding a driveway, a deck, or a fence to your house wash, expect a longer single appointment rather than several short ones. You can see the details on our driveway cleaning, deck and patio cleaning, and fence cleaning pages.
What Happens During Your Appointment, Step by Step
A lot of the time on any job goes to steps that aren’t the actual spraying. Walking through the stages shows where the minutes go.
- Arrival and walkthrough (about 10 to 15 minutes). We confirm which surfaces we’re cleaning, point out problem areas, and set expectations for the timeline.
- Prep and protection. We close windows, tuck towels behind exterior doors, move furniture as needed, and protect plants. We ask that pets and children stay indoors while we work.
- Apply detergent and let it dwell (5 to 10 minutes per section). The cleaning solution needs a few minutes to lift algae and mold off the surface. This pause looks like downtime, but it’s the part doing the real work, and it’s the main reason a proper wash isn’t instant.
- Rinse. We rinse from the top down at low pressure on siding, letting the clean water carry the loosened grime away.
- Detail and final walkthrough. We spot-check the work and confirm you’re happy before we pack up.
Because the detergent dwell does the heavy lifting on a soft wash, the timeline is built around chemistry rather than brute force. The low pressure protects your siding while the solution clears the growth.
The Second Clock: How Long a House Takes to Dry After Washing
The appointment is only the first clock. The second is how long your surfaces take to dry once we’ve left.
Drying depends on the material and the weather, and the table below shows what to expect by surface. Madison’s climate stretches the window on certain surfaces, since lake-area humidity and walls that sit in shade hold moisture longer.
| Surface | Typical Dry Time | Faster or Slower |
|---|---|---|
| Vinyl or aluminum siding | About 24 hours | Faster in sun and wind |
| Concrete driveway or patio | 24 to 48 hours | Shaded concrete dries slower |
| Wood deck or fence | 48 to 72 hours | Porous; north side is slowest |
Surface water clears quickly, so you can usually walk on a driveway or move around the yard the same day even though full drying takes longer. If you’re planning to paint or seal a surface afterward, dry time matters even more, so let us know at the walkthrough and we’ll give you a realistic window to plan around.
A Typical Madison Appointment, Start to Finish
Here’s how the numbers stack up on a real-world job. Picture a roughly 2,000 square foot two-story home in a neighborhood like Middleton or Fitchburg, booked for a soft-wash siding cleaning plus a two-car driveway.
The walkthrough and prep take about 20 minutes. The siding soft wash, including detergent dwell, runs around 2 hours. The driveway with a surface cleaner adds another 45 to 60 minutes. A final rinse and inspection wrap it up in about 15 minutes.
All in, that’s roughly 3 to 3.5 hours on site, finished in a single visit. The siding is dry to the touch within a day, and the driveway is usable the same day and fully dry within 24 to 48 hours. Every home is a little different, so treat this as a realistic example rather than a fixed quote.
Frequently Asked Questions
Do I need to be home the whole time?
You don’t have to stay for the entire visit, but it helps to be there at the start so we can confirm the surfaces and any problem spots. We just ask that windows are closed and pets are indoors before we begin.
Does soft washing take longer than a high-pressure blast?
It includes a short dwell time built in, which a high-pressure blast skips. That extra few minutes per section is what kills algae and mold at the root instead of just knocking the surface layer off, so the clean lasts far longer.
Can my whole house be washed in one day?
Almost always, yes. Nearly every residential job in Madison is finished in a single morning or afternoon visit.
